Vinegar spray (use with caution, test first).

Diluted white vinegar can act as an odor neutralizer when lightly sprayed over carpets. Vinegar's acidity helps to break down alkaline odor molecules, effectively neutralizing smells. However, due to its acidic nature, it's crucial to test vinegar in an inconspicuous area first to ensure it does not affect the carpet color or material. Proper ventilation is necessary to avoid a temporary vinegar smell, which dissipates as it dries, taking odors with it.
